IMPROVEMENT IN CHEESE-VATS.

Specification forming part of Letters Patent No. 34,511, dated February25, 1 862.

.To all whom it may concern:

Beit known that I, FRANCIS X. MANAHAN, of Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Oheese-Vats; and I do hereby declare that the following is afull,clear, and exact description of the same, reference being had tothe'annexed drawings, making apart of this speciiication, in which-Figure l is a side sectional View of my invention, taken in the line @amof Fig. 3; Fig. 2, a transverse vertical section of the same, taken inthe line y y of Fig. l; and Fig. 3, a horizontal section of the same,taken in the line e' z of Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relatesto an improved arrangement of means for heatingthe milk-vat, or rather its contents, to a proper temperature by meansof a boiler or heater so arranged in connection with pipes and cocks anda supplemental or hot-water chamber that the contents of the milk-vatmay be heated and graduated with great exactness or nicety, and theresult attained with the least possible expenditure of time and fuel.

The invention also relates `to an improved means employed for keepingthe hot-water chamber tight around the cock or faucet through which thewhey is drawn from the milk-vat.

To enable others to make and use my invention, I will proceed todescribe it.

A is a rectangular box, which'may be constructed of sheet metal, of anyproper size, and supported at a suitable height by legs B. The box A hasa smaller box O at one end of it, the box O being provided with a coveror lid D and having a cock E at its lower part, as shown in Fig. 3.

Within the box A there is tted a milk-vat E, which has inclined sidesand is provided at its upper edges with strips @,which rest on strips bat the upper edges of the box A. The milk-vat E may be constructed ofsheet metal like the box A, although sheet-iron galvanized wouldprobably be a better material. The milk-vat E is suciently smaller thanthe box A to allow of the latter holding a requisite quantity of water,and the vat E has a cock F fitted to one end of it in a novel way, asfollows: The vat E has a tube G attached `to one end of it, said tubecommunicating with the interior of the vat and having a screw-thread ccut on its outer surface. The tube G is provided with a liange d, which,when the vat E is adjusted in proper position, abuts` against the innerside of the box A, as shown clearly in Fig. l.

The cock F vmay be of usual construction, with the exception that itsback end is provided With a flange e, that is tted within a socket H,which has an internal screw e 'and a lip e at its outer end, said lipfitting over the iange e. By screwing this socket H `on the tube G thesocket is snugly adjusted to the tube, packing f being interposedbetween the tube G and the inner end of the cock F,

- as shownclearly in Fig. 1. Packing g may also be interposed betweenthe socket Hand the side of box A. By this arrangement it will be seenthat the cock F may be readily detached from the vat E to admit of thelatter being removed from the box A, and also readily attached whennecessary, so as to be perfectly water-tight and prevent all leakagefrom box A.

I represents a boiler,whichv is of cylindrical form and placedlongitudinally underneath the box A. The flue J of the boiler passescentrally throughit, and K K' are two pipes which form a communicationbetween the boiler I and the box A. The pipe K communicates with theupper part of the boiler and the pipe K with its lower part, and eachpipe is provided with a cock,which are designated by h h. The cock h ofthe pipe K is athreeway cock and is fitted in K at the junction of apipe L, which forms a communication between K and the box O. The upperend of the pipe K communicates directly with the interior of the box A;but'the pipe K communicates with a longitudinal pipe M, which is of flatform and perforated at its sides, as shown at t', and extends nearly thewhole length of box A.

N is a pipe, which extends upward from the front part of the boiler Iinto box O, and `is bent therein in Siphon form. This pipe Nadmits ofthe escape of air from boiler I when the latter is being filled. O is apipe, which communicates with the lower part of boiler I and box O. Pisa discharge-pipe at the lower part of the boiler. Q is a cock at one endof the box A.

The operation is as follows: The boiler I is lled with water by pouringthe same through a funnel R at one end of box A, the cock h of pipe Kbeing open and the cock h so adjusted that the pipes L and K are incommunication. The boiler I is filled and the Water allowed to extend toa proper height in A and C, the Water of course being on a level inboth. The fire is then kindled in the fire-chamber of boilerI and thecock h adj usted so that the pipe K will commmunicate' with the boiler Iand box A. The milk is then poured into the Vat E and the water, heatedto 86 Fahrenheit, the rennet added,

and the separation of the whey and curd effected. During this heating ofthe milk the circulation of water through the boiler I, box A, and pipesK K is indicated by the arrows l. After the separation of the curd andwhey in vat E the operator turns the cock h ofthe pipe K so that thepipes L and K conlmunicate witheach other, and the cock h of 'pipe K isclosed. This aords a circulation of water through box C, pipes O, L, andK, and the boiler I. Additional water is put in box C, and the water inC will be heated while the operator is cutting up the curd in Vat E.During this operation it will be perceived that the fire is not idle, asthe Water in C `is being heated for the purpose of the subsequentoperation of scalding-that is to say, the subjecting of the contents ofthe Vat E to a much higher temperature than before, 104 Fahrenheit.After the curd is cut up 'and the contents of vat E mixed the cocks h hof pipes K K are turned to their former' position and the water in O ofcourse raises the height of the water in A and increases itstemperature, so that it will be quickly raised to the desiredtemperature-104o Fahrenheit--for scalding. After the scalding operationis completed the whey is drawn from the vat E through cock F.

The perforated pipe M is an essential feai ture of the invention, as itcauses the hot water from pipe Kto be equally distributed over thebottom of the box A, as Will be understood by referring to Fig. 3. Thearrangement of the pipes K K, O L, and cocks h h is important, as theoperator has perfect controlover the water so far as the directing ofits course is concerned through the boxes A nally at the bottom of thebox A and communicating with the pipe K, substantially as shown, for thepurpose of equally distributing the ascending hot water from boiler I,as set forth.

2. The arrangement of the pipes K K', cocks h h', and pipes O L with theboiler I, Water-boxes A O, and milk-vat E,'as herein shown anddescribed.

3. Securing the cock F to the milk-vatE through the medium of the pipeGand screwsocket H, arranged substantially as shown vand described.
